Being able to make repairs around the home is a valuable skill to have, saving both money and time, and also giving a sense of satisfaction. Many domestic plumbing tasks can be carried out by anyone who’s reasonably good with their hands — leaking faucets, malfunctioning toilets, blocked pipes — you feasibly can fix all of these yourself, especially in this age of instant information and tutorials over the internet. However, there are some types of repair that should definitely be left to the plumbing experts, and here are five examples.

Water HeatersAside from routine cleaning, anything involving a water heater is probably a job for professionals. When working with a heater, you’ll be dealing with water, electricity, and probably gas or oil. If you make one mistake, the consequences can be severe. Also, an amateur is unlikely to have all the right tools to ensure safety, such as those needed to detect gas leaks or carbon monoxide emissions, and your home insurance may not cover any damage caused by faulty DIY repairs.

Sewer RepairNot only is this an unpleasant job that you might prefer to give to someone else, but you could easily make things worse by tackling it yourself. What may seem like a simple leak could in fact be caused by a blockage or other problem deeper within the system. Without the right tools, such as cameras and other inspection devices, you might only apply a band aid with your fix. If you don’t address the main problem, you risk a more severe issue at a later stage, possibly involving the expense and disruption of digging up your whole yard.

Pipe Repairs or ReplacementTightening a loose joint is one thing, but tackling anything more complicated is risky. A pipe system is only as strong as the weakest part. Without the right tools to ensure a proper job is done, you risk failure when the system is brought up to pressure. With water pipes, this can be a damaging leak that’s quickly noticed and fixed. With gas pipes, you might not even realize there’s a problem until disaster strikes.

Major Leaks

If you’re faced with a pipe spraying water across the room, it’s time to turn off the main supply and call in a professional. It might seem a simple matter to fix the obvious fault with a replacement joint or a spot of soldering, but this might only be the tip of the iceberg. If a major leak has occurred, it’s likely that other parts of the system are also in a similar state of wear and tear, and could be close to failure, possibly in a much more damaging and hard-to-fix location. A plumber will not only deal with the immediate problem, but also will check on the health of the rest of your pipework to prevent future failures.

Multi-Occupancy BuildingsIn most jurisdictions, amateur plumbing repairs are illegal in buildings where other families also live, and so a certified professional needs to be used. Whether this restriction would ever be enforced over a simple leaking tap is of course your judgement to make, but certainly for any more major work, then it’s a point to be aware of if you want to avoid legal problems down the line.

Many plumbing repairs are fairly simple, and easier and quicker to carry out yourself rather than call in someone else. However, if you’re at all unsure, and when the consequences of a mistake can be serious, it pays to consult a professional. With most good plumbers now offering free call-outs and estimates, you’ve nothing to lose by getting an expert opinion.
